Thermal imaging
Thermal Imaging
Thermal imaging (pronunciation: /ˈθəːm(ə)l ˈɪmɪdʒɪŋ/), also known as infrared imaging or thermography, is a method of capturing the heat emitted by objects in the form of infrared radiation. The technology was originally developed for military use during the mid-20th century, but has since found applications in a variety of fields, including medicine.
Etymology
The term "thermal imaging" is derived from the Greek word "therme", meaning heat, and the Latin word "imago", meaning picture. It refers to the process of creating a visual representation of heat or temperature.
Medical Applications
In the field of medicine, thermal imaging is used for a variety of diagnostic and therapeutic purposes. It can be used to detect inflammation, monitor blood flow, and identify areas of the body that are experiencing abnormal heat patterns, which can be indicative of disease or injury.
Some of the specific medical applications of thermal imaging include:
- Breast Cancer Detection: Thermal imaging can be used as a non-invasive method of detecting early signs of breast cancer. It can identify areas of increased heat in the breast tissue, which may be indicative of a tumor.
- Diabetes Management: Thermal imaging can be used to monitor blood flow in the extremities of patients with diabetes. This can help to identify areas of poor circulation, which can be a sign of diabetic neuropathy.
- Rheumatology: Thermal imaging can be used to detect inflammation in patients with rheumatic diseases, such as rheumatoid arthritis.
Related Terms
- Infrared: The type of radiation that is detected by thermal imaging cameras.
- Radiation: The emission of energy as electromagnetic waves. In the context of thermal imaging, this refers to the infrared radiation emitted by objects.
- Thermography: Another term for thermal imaging, often used in the context of medical applications.
